Starting ij using properties

You can set ij properties in any of the following ways.

Remember: ij property names are case-sensitive, while commands are case-insensitive.


The following examples illustrate how to use ij properties.

To start ij by using a properties file called, use a command like the following (with the addition of the file paths):

java -jar derbyrun.jar -p

To start ij with an ij.maximumDisplayWidth of 1000:

java -Dij.maximumDisplayWidth=1000 -jar derbyrun.jar

To start ij with an ij.protocol of jdbc:derby: and an ij.database of sample, use the following command:

java -Dij.protocol=jdbc:derby: -Dij.database=sample derbyrun.jar

To start ij with two named connections, using the ij.connection.connectionName property, use a command like the following:

java -Dij.connection.sample=jdbc:derby:sample \
-Dij.connection.History=jdbc:derby:History \
-Dderby.system.home=c:\derby\demo\databases \
-jar c:\derby\lib\derbyrun.jar

To see a list of connection names and the URLs used to connect to them, use the following command. (If there is a currently active connection, it will appear with an asterisk (*) after its name.)

ij version 10.13
ij(HISTORY)> show connections;
HISTORY* -    jdbc:derby:History
SAMPLE -     jdbc:derby:sample
* = current connection
